Abstract

Selon l'invention, afin de garantir une liaison fiable entre un blindage (16) d'un câble haute tension (2) et un boîtier (4), en particulier pour un véhicule électrique ou hybride, un blindage (16) du câble (2) est serré entre un manchon interne (20) et un manchon de contact (18), un raccordement électriquement conducteur au boîtier (4) étant formé par l'intermédiaire dudit manchon de contact (18). Ainsi, le manchon de contact (18), qui se présente sous la forme d'un manchon de sertissage, comporte une couronne formée de languettes élastiques (32). Le manchon interne (20) est également serré à l'aide d'une gaine (30) du câble (2) afin d'obtenir un câble de décharge. En outre, le câble (2) peut être fixé sur le boîtier (4) de préférence par l'intermédiaire d'une liaison par enfichage/encliquetage simple.
